To compare the chemical change of Paeoniae Radix Alba (PRA) after vinegar-baking processing, as well as the effect of vinegar types exerted on the processing, 1H NMR-based metabolomic approach combined with multivariate statistical analysis was used to investigate the different metabolites between the raw and two vinegar-baked PRA. More than thirty metabolites were identified in the 1H NMR spectrum of PRA, and the multivariate statistical analysis showed that raw and two vinegar-baked PRA could be separated obviously. After vinegar-baking, the contents of isoleucine, lactate, alanine, arginine, albiflorin, and 5-hydroxymethyl furfural (5-HMF) elevated, while those of sucrose, paeoniflorin and its analogues (calculated by benzoate) decreased. The chemical compositions of two vinegar-baked PRA were also different. Shanxi vinegar- baked PRA showed higher levels of leucine, isoleucine, valine, and albiflorin, while rice vinegar-baked PRA contained more sucrose and paeoniflorin's analogues (calculated by benzoate). And the chemical changes in Shanxi vinegar-baked PRA were greater than those of rice vinegar-baked PRA. The results revealed the chemical differences between raw and vinegar-baked PRA, as well as the influence of vinegar type on processing, in a holistic manner, the results obtained suggested that the correlations between the chemical change and the drug action after processing, as well as the vinegar type used in processing, should be further studied.

Medical Journal of Chinese People's Liberation Army 2019;44(8):676-681
Objective: To observe the characteristics in changes of cystatin C (Cys C), total cholesterol (TC), lipoprotein a [Lp(a)] and proteinuria levels and their significance in patients with cerebral small vessel disease (CSVD). Methods: This was a retrospective study consecutively recruiting 316 patients with CSVD from September 2016 to August 2018 at Lanzhou University Second Hospital, including 113 with white matter hyperintensity (WMH), 101 with lacunar infarction (LI) and 102 with cerebral microbleeds (CMB). One hundred and two elderly people without abnormal head MRI changes and positive signs of nervous system were selected as the control group. Cys C, TC, Lp(a) and proteinuria levels were measured and compared between the groups. Results: Serum Cys C and proteinuria levels in CSVD group [(0.9 ± 0.2) mg/L, 99(31.2%)] were all significantly higher than those in control group [(0.8 ± 0.2) mg/L, 12(11.8%), P<0.05]. While, serum TC levels in CSVD group [(3.9 ± 1.0) mmol/L] was significantly lower than those in control group (P<0.05). Subgroup analysis showed that serum Cys C and proteinuria levels in the WMH group [(0.9 ± 0.2) mg/L, 33(29.2%), respectively], the LI group [(0.9 ± 0.2) mg/L, 36(35.6%), respectively] and the CMB group [(0.9 ± 0.1) mg/L, 30(29.4%), respectively] were significantly higher than those in control group (P<0.05). While, serum TC level s in WMH group, LI group and CMB group [(3.9±1.1) mmol/L, (3.9±1.0) mmol/L, (3.8±0.8) mmol/L, respect ively] were significantly lower than those in control group (P<0.05). After adjustment for confounding factors, multiple logistic regression analysis showed that Cys C and proteinuria were independent risk factors for CSVD (P<0.05). Additionally, subgroup analysis showed that TC was independent protective factor for CMB (P<0.05), Lp(a) was independent risk factor for LI (P<0.05). Conclusions: Cys C, Lp(a) and proteinuria may be risk factors for CSVD, but may not carry the same weight for WMH, LI and CMB. Meanwhile, TC is an independent protective factor for CMB.

Objective To investigate the distribution modes of NOS nerves and interstitial cells of Cajal (ICCs) in myenteric plexus of human fetal intestine. Methods Small intestine samples from 12 fetuses were collected for the preparation of whole mount preparations and cryo sections examined by immunocytochemistry for c kit receptor tyrosine kinase and histochemistry for NADPH diaphorase. Results ICCs associated with the myenteric plexus in the fetal small intestine were observed in the shape of spindle or ovoid with two to three slender processes forming an independent and complete cellular network. While NOS positive nerves, which constitute the main neuronal component of ganglia, connecting strands, and nerve fibers, were found within the circular muscle layer and myenteric plexus of the small intestine and the latter was especially rich of this kind of nerves. Most of these positive neurons were Dogiel I type neurons and they often gathered in cluster in the ganglia. Each ganglion contained several to dozens of NOS positive neurons. Although no colocalization of ICCs and NOS positive nerves was found by double staining of whole mount preparations and cryo sections, they were closely distributed. Conclusion Our results indicate that NO released by myenteric plexus, an inhibitory neurotransmitter, may possess the function of regulating ICCs and smooth muscle in late stage of the fetus.

A systematic review was undertaken, including studies that evaluated the incidence of the blood system adverse events of Tripterygium wilfordii (TWP). Medline, Embase and the Cochrane library were searched for relevant studies, including RCT, cohort studies and case series, of patients treated with TWP published in English and Chinese from inception up until May 25th, 2013 with the keywords including "Tripterygium wilfordii", "toxicity", "reproductive", "side effect", "adverse", "safety" and "tolerability". Relevant information was extracted and the incidence of the blood system adverse events was pooled with MetaAnalyst software. Besides, subgroup and sensitivity analyses were performed based on age, mode of medicine, observation time and disease system. According to inclusion and exclusion criteria, a total of 49 articles were included in the meta-analysis, they were split into 54 researches incorporated in the analysis. There is a large degree of heterogeneity among the studies, so data was analyzed using random-effects model and the summary estimates of incidence of the blood system adverse events was 6.1%. The weighted combined incidence of three major blood system adverse events were white-blood cells decreasing 5.6% (95% CI, 4.3% - 7.3%), hemoglobin decreasing 1.7% (95% CI, 0.5% - 5.0%) and platelet decreasing 1.8% (95% CI, 1.0% - 3.1%), respectively . Sensitivity analyses based on 45 studies with high quality showed the combined value was close to the summary estimate of total 54 studies. The current evidence indicates that the incidence of the blood system adverse events induced by TWP was high; attentions should be paid on to the prevention and treatment of the blood system adverse events.
